  • Patent number: 10365809
    Abstract: A display device includes a housing, an operation surface, a position sensor, a press sensor, and a display unit. The position sensor detects a touched position on the operation surface. The press sensor detects a press on the operation surface. The display unit displays an image. When the press sensor detects a pressing amount not smaller than a first threshold, a control unit sets, as a rotation axis of a three-dimensional image, a direction orthogonal to the sliding direction of the touched position detected in the position sensor. The control unit then rotates the three-dimensional image in accordance with the sliding direction of the touched position detected in the position sensor.
